Question 10

How do I set video fade‑out and audio fade? Global vs per‑scene?

Accepted Answer

Global default: In Settings, under "Playback Defaults", enable "All Video Fade Out On" and "All Audio Fade Out On" so that in the last ~1 second of playback all scenes get video fade‑out and audio fade. Per‑scene override: Right‑click a scene card and enable "Video Fade Out Off" or "Audio Fade Out Off" to disable fade for that scene only.

Question 11

What automatic playback modes exist? How do they relate to loop?

Accepted Answer

Loop: Right‑click scene card → "Loop", or in the Layer panel right‑click a layer → "Enable Loop". Playback restarts from the beginning when it ends. End‑to‑scene: Scene right‑click → "Auto To 1", "Auto To 2", etc. When playback ends, the specified scene is cut to and played. Mutually exclusive with Loop; enabling Loop clears End To. Auto Next: When enabled, after playback ends the next scene is cut to automatically. Mutually exclusive with Loop and End To.

Question 12

What is the output layer order for video, audio, images, and PDF?

Accepted Answer

Within each scene, layers are ordered by the list: list order = draw order (top of list = top layer, drawn last). Typically put video on lower layers and images/PDF on upper layers. In the Layer panel you can drag or use Move Up / Move Down to reorder; lower layers are drawn first, upper layers on top.

Question 13

How do I save a project? Can I package it? What should I watch for?

Accepted Answer

Save with media: Cmd+S or File → "Save with file" — saves the project as .pmix (JSON) and copies referenced media into an _media folder next to the project file, using relative paths so the project is portable. Save project only (PJ only): File → "Save PJ only" — saves only project data (scenes, settings); media paths are written as relative if they are already under the project directory. Note: When moving to another machine, use "Save with file" and copy the whole project folder including _media. If media is missing on open, ensure paths are valid or replace files manually.

Default shortcuts (all editable in Edit → Hotkey Editor): 1–9: Cut scene 1–9 to Program Enter / C: Cut to Program A / M: Select AUTO/Mix transition (then Enter to run) B / F: Fade to Black on/off Space: Play/Pause S: Stop Left / Right: Previous/next scene (send to Preview); with Space held, previous/next PDF page F12: Toggle external output Cmd+N New, Cmd+O Open, Cmd+S Save, Cmd+Q Quit
